Surgical and nonsurgical treatment of acute ankle sprains.

In the treatment of eversion injuries or tears of the medial structures, exact anatomic restoration is mandatory, and this must be accomplished by either closed reduction or surgery. The treatment of lateral ankle ligament injuries is usually cast immobilization, taping, or a cast-brace. Surgical treatment of lateral ankle ligament sprains is performed only on those highly competitive young individuals who require an almost normally functioning ankle.

Current concepts in the role of steroids in the treatment of sprains and strains.

With the development of nonsteroidal anti-inflammatory drugs, the use of corticosteroids in the treatment of sprains and strains has greatly diminished. They are used occasionally in the treatment of tendinitis in various areas of the body, but they are not used for ligamentous sprains and muscle strains. Injection of corticosteroids into ligaments, tendons and joints is often quite controversial and most clinicians have abandoned their use in the treatment of common athletic injuries.

Milking vacuum influencing indicators of udder health.

In 23 first-calf heifers we ascertained effects that milking vacuums of 34, 42.5, and 51 kPa had on udder health by percentage of quarter-samples positive for Staphylococcus aureus, total counts of bacteria on blood agar, teat end scores, California Mastitis Test, and direct microscopic somatic cell count. Measures were higher for 51 kPa than for 34 or 42.5 kPA. Samples from cows milked at 42.5 kPa had a lower percentage of samples positive for Staphylococcus aureus, lower total count, lower California Mastitis Test, and lower direct microscopic somatic cell count than samples from cows milked with 34 kPa. Test end scores increased with increase in milking vacuum. Approximately 49% of the samples from cows milked with 51 KPa were positive for Staphylococcus aureus compared with 19.9 and 16.7% for 34 and 42.5 kPa. Milking vacuum of 51 kPa resulted in the highest percentage of cows with three (44.5%) and four (24.1%) quarters positive for Staphylococcus aureus. A milking vacuum of 51 kPa could increase mastitis in a herd having Staphylococcus aureus as the prevalent microorganism causing mastitis.

[The development of the American carcass rendering industry (author's transl)].

The American rendering organization is different from that in Europe, it has historycally developed as an industry separate from slaughter houses, it has grown and waxed very profitable on a world wide basis, and finally it is now under technological attack which may eventually fundamentally change it and make it more like the organization of rendering that you have in much of Europe after all.

"Normal" talar tilt angle.

A study to determine the degree of normal talar tilt in individuals with no history of ankle injuries was performed on 404 ankles of 202 midshipmen at the U.S. Naval Academy. Manual inversion stress roentgenograms were used to test this group of young healthy adults, most of whom were males. Of the 404 ankles tested, only 39 (9.7%) had any measurable talar tilt and only 7 ankles (1.7%) had a tilt over 5 degrees. Normal talar tilt does not range to 23 degrees. A normal ankle in a healthy young adult with no history of trauma has a small probability of having any talar tilt. When stress roentgenograms are used to evaluate a fresh lateral ankle ligament sprain in this type of individual, there is a very high probability that talar tilt over 5 degrees would represent significant injury to one or more of the lateral supporting structures.

Interaction of cromolyn sodium in aqueous solution with magnesium ions.

The interaction of the antiasthmatic drug cromolyn sodium with Mg2+ ions in solution was studied. Selective ion electrode and torsion viscometer measurements were used to establish the degree of interaction. At the concentrations studied, the cromolyn ion had no more affinity for Mg2+ than SO42-. However, thixotropic gels were formed between 4 X 10(-2) M cromolyn sodium and 4 X 10(-4) Mg2+. At lower concentrations of Mg2+, viscosity still increased significantly. However, when the cromolyn concentration was lowered, the increase in viscosity was much less marked.

The degenerative effects of partial and total resection of the medial meniscus in dogs' knees.

An experimental effort to determine the degenerative effects in the articular cartilage of the knee joint caused by meniscectomy was performed by doing partial and total meniscectomies on the medial compartment of dogs' knees. Gross and microscopic pathological changes in teh articular cartilage were studied by sacrificing the dogs at intervals of three to ten months. Results indicated that meniscectomy is not a benign procedure, and the removal of a meniscus in itself can lead to degenerative changes in the knee joint. Partial meniscectomy leads to less severe degenerative changes with the degree of change directly related to the amount of meniscus removed. In total meniscectomies when meniscus regeneration occurred, the cartilage surfaces where the meniscus had regenerated were protected. The degree of degenerative change was directly related to the amount of fibrocartilage that remained absent. Therefore, the knee menisci function to protect the articular cartilages from degenerative damages, but the exact mechanism of this is unknown.
